IMPROVEMENT IN PERFORATlNG-STAIVIPS.

Specification forming part of Letters Patent N 0. 211,627, dated January28, 1879; application lled November 5, 1878.

To all whom it may concern:

Be it known that I, WALLACE W. GELATT, of Washin gton city, District ofColumbia, have made certain new and useful Improvements in StampCanceling and Imprinting Devices for Marking and Canceling Postage andother Stamps, ot' which the following is a specification:

The object of this invention is to improve upon the canceling andpost-marking stamps now in use 5 and it consists in the constructionofthe device, as will be fully hereinafter described'.

In the drawings, Figure lis a vertical view ofthe device. Fig. 2 is aplan view of under side of device. Fig. 3 is a plan or top view belowline x.

A represents the handle, made of any suitable material. B is a metalband, into which handle Ais firmly inserted, having slots therein oneach side to admit of the free passage of arm C. C is a reciprocatingarm or Walking-beam, pivoted, at or about its center, in handle A, asseen in Fig. l, one end of which passes through a slot in the upper endof the stamping-die rod, an d pivoted therein by pivot-pin p. The otherend ot' arm C has within and upon its semicircular hand stud c, workingin a spiral groove upon cylindrical rod G.

D is a stationary bar, rigidly attached to handle A, the outer ends ofwhich bar have holes therein to freely admit of the passage up and downof the stamping-die rod and the cylyndrical rod attached to the cutteror canceling-wheel. E is a rod, attached rmly to the stamping-die, whichrod reciprocates freely through an orifice in the outer end of bar D,and is fastened to arm C, as hereinbefore described. F is thestamping-die, rigidly attached to rod E at its lower extremity, and hasathumb-screw, j', passing into it for the purpose of rmly holding thetype, upon which is the date of stamping. G is a cylindrical rod, havinga spiral groove therein, which rod, like rod E of the stamping-die, alsopasses freely through an orifice in the outer end of bar D, and is heldin position by pin l) upon cylindrical rod G. H is a rile-faced cutteror canceling-wheel, rigidly attached to the lower end of cylindrical rodG. h is a spiral groove cut in-rod G, and in which stud c of thereciprocating arm C operates, by means of which reciprocation stud cimparts rotary motion to file-faced cutter or canceling-wheel H as it(the stud c) passes up and down in spiral groove h. J is a plateextending from the inner side of rod E to the inner side ot cylindricalrod G, and located upon the top of the stamping-die F andcanceling-wheel H. Each end of said plateJ is semicircular in form, soas to nicely ht laround said rods E and G, and is held in position byspiral spring j, encircling a rod iirmly inserted in handle A, as seenin Fig. 1.

K is a rod, around which spiral spring j twines, and is held in positionby its upper end'bcing firmly embedded in the lower end of handleA,while its lower end passes through a hole in plate J, and is ofsufficient length to remain at all times below plate J, thereby actingas a holding device to the better keeping ot' plate J inits properplace. Lis a hollow square cut in the under side of the stamping-die F,and of sufficient depth to admit of the insertion of the type forimprinting the date of stamping, which type are held firmly in positionby thumb-screw f in stamping-die F.

Having thus described my invention, what I claim is- In aperforatingstamp, handle A, band B, reciprocating arm C and itspivot-pin p, stud c, working in spiral groove h, stationary ba-r D, rodE, stampingldie F, with its hollow recess L, thumb-screw f, cylindricalrod G, pin I), cutter-wheel H, plate J, rodV K, spiral spring j,substantially in the manner shown, as and for the purpose described.
